title: Packages
---

The `@typescript-eslint/*` packages are all stored in [our GitHub monorepo](https://github.com/typescript-eslint/typescript-eslint).
The monorepo is built with [Lerna](https://lerna.js.org) and [Nx](https://nx.dev).

Each page in this section corresponds to a package we intentionally expose to users.
They are:

- [`@typescript-eslint/eslint-plugin`](./packages/ESLint_Plugin.mdx): An ESLint plugin which provides lint rules for TypeScript codebases.
- [`@typescript-eslint/eslint-plugin-tslint`](./packages/ESLint_Plugin_TSLint.mdx): An ESLint plugin that allows running TSLint rules within ESLint to help you migrate from TSLint to ESLint.
- [`@typescript-eslint/parser`](./packages/Parser.mdx): An ESLint parser which allows for ESLint to lint TypeScript source code.
- [`@typescript-eslint/rule-tester`](./packages/Rule_Tester.mdx): A utility for testing ESLint rules.
- [`@typescript-eslint/scope-manager`](./packages/Scope_Manager.mdx): A fork of [`eslint-scope`](https://github.com/eslint/eslint-scope), enhanced to support TypeScript functionality.
- [`@typescript-eslint/typescript-estree`](./packages/TypeScript_ESTree.mdx): The underlying code used by [`@typescript-eslint/parser`](./packages/Parser.mdx) that converts TypeScript source code into an [ESTree](https://github.com/estree/estree)-compatible form.
- [`@typescript-eslint/utils`](./packages/Utils.mdx): Utilities for working with TypeScript + ESLint together.
